PELATIHAN ADVANCED OF ROTATING EQUIPMENT
TRAINING ADVANCED TROUBLESHOOTING OF ANTI-FRICTION BEARINGS
DESCRIPTION Pelatihan Advanced Troubleshooting Of Rotating Equipment
This Advanced Programme for industry aims to convey the latest thinking and best practice of machinery vibration monitoring and analysis via lectures, case studies, video films, friendly software and programme activities. The programme gives a detailed advanced treatment of the detection, location and diagnosis of faults in rotating and reciprocating machinery, using vibration analysis. Industrial case study examples are used throughout the programme to emphasise key points and to underline the relevance and applicability of the topics being addressed.
The programme will provide a refreshment of knowledge for existing condition monitoring practitioners, and it will provide a solid foundation for technologists moving into a machine monitoring and diagnostic role.
